SRP Ti water bottle cage bolts work well, Cambria has them for $8.95 per pair.http://www.cambriabike.com/shopexd.asp?id=9189
They have low profile heads that won't hit your fork leg, like a regular socket head cap screw can. Probably not an issue on your Jones fork, but still something to keep in mind.

I bought some parts off of him last November when I just happened to be in Toronto for business. I asked him if I could meet up with him to avoid paying shipping costs and he didn't even hesitate at inviting me to his residence... even though it was after 10pm.

A guy from england also sells em on ebay, got mine from him.. no problems and he supplies a free tool (bits_4_bikes) he also sells heaps of other Ti bolts and carbon bits and pieces... well worth a look!
